No standby power on these sets after a power loss is usually a bad IC at location U203 on the back of the power supply board. It's a Fairchild FAN6755 8-pin surface mount IC... A cheap, easy fix if you have basic soldering skills...
Hello, Doing something like that,chances are you blew the powersupply , and hopefully nothing else. You can replace just the powersupply 50 dollars or less, if that doesn't fix it will have have to be serviced.
NO Electrical power? Them Power Supplies sometimes goes out at the craziest times. Normally if a powersupply is faulty, you just replace it, with another one . The problem comes in, when you need a speciality type of powersupply instead of your good ole stand by ATX form factor. It appears to me, you have a faulty 250 Watt power supply that is design for that system. You say it's IW-P250A3 Power Supply and you want to know the cost of the part replacement? I seen for prices like $30.00 dollars of as high as $117.00 dollars. I would check with your local Tech Store, or check out ebay, also maybe a tech site like directron or newegg for pricing. Good luck on your adventure with replacing the PSU. Hope this help.
chances are it's a capacitor, if it went on a power supply. get the power supply back and see if the main capacitor is puffy. you can fet one at almost any electronics store. otherwise, replace the whole power supply.
The problem will definitely be with your powersupply , but before investing in a new one - open up the unit by taking off the top cover and replace the fuse that is on the powersupply - this is 90% of the time the only problem.
If this doesn't work , please supply me with the part number on the part and also with your country you are in and I'll send you the pricing and dealer's contact details.
it was not necessry to replace so many parts if you go as per proper procedure.please proceed as
1 isolate horizontal output section
from power supply & make power supply ok.
2 if it becomes ok check hor osc,driver&h/output section.
3 if it is ok connect power input to hor.section which was isolated.
4 check for loose contact or print.
5 put on tv .
